An ex-UK Independence Party (UKIP) MEP says that the party's climate change scepticism was callow and so eccentric that party press officers often had to contradict the views of its climate spokesman, Lord Monckton.

But Andreasen said that she doubted whether UKIP had received any funding from the energy intensive sector, and UKIP too denies this. "If they really had somebody financing this, they would have done it better," she told EurActiv.

"The typical [people] dealing with climate change were the MEP Godfrey Bloom and Lord Monckton, who was seen even within the UKIP as eccentric," she added.

Monckton famously dressed up as a Bedouin and occupied Burma's seat at the UNFCCC climate summit in Doha last year. He lectured delegates about the lack of global warming in the last 16 years for about a minute before being ejected and banned from future UN summits for life.

Screaming and shouting 'nonsense'

"More than once I saw people internally - even the press office - contradicting what he was saying," Andreasen continued. "Godfrey Bloom also used to scream and shout in the [European Parliament] plenary about the nonsense that climate change represented."

Bloom's environment spokesman post for UKIP was recently taken up by Roger Helmer who, in 2009, accused the Church of England of having "abandoned religious faith entirely and taken up the new religion of climate alarmism instead".

But Bloom, a financial economist by trade, is still a substitute member of the European Parliament's environment committee, and an influential voice on climate policy within UKIP, which currently polls 17% in British voting surveys.

Contacted by EurActiv, he dismissed Andreasen's depiction of UKIP climate policy as "one of her usual rather wild accusations".

"She has never expressed any position on climate change in all the years she's been with us so I am not sure where she's coming from," he said.

A matter of fact

Bloom argues that the EU's "disastrous" shift to renewable energy endangers the security of electricity supplies, and calls for a Royal Commission to examine climate science.

"It became clear in 2005 that the world was not warming and we have been monitoring it closely ever since," he said. "There are no independent scientific institutes in the world which have not conceded that there has been no global warming for 15 years. That's a matter of fact, not opinion."

However, Kevin Trenberth the lead author of the 2001 and 2007 IPCC scientific assessments on climate change told EurActiv that the panel had not made any statement on global warming over the last 15 years. A draft IPCC report to be published next year though would contain "multiple statements" reflecting global warming in that period, he said.

After installing a new computer model in January, the UK's national weather service did round downwards a global temperature projection for the period up to 2017 by 20% - from 0.54C, to 0.43C above the long-term average.

Even so, surveys indicating that at least 97% of scientists attribute global warming to greenhouse gas emissions should not be used to silence dissenters, Bloom says, citing the 16th Century scientific consensus against Copernicus.

Climate scientists though, say they are not convinced by this analogy, especially when Bloom also attributes last year's record Arctic sea ice melt to "a natural cycle which has grown and receded over the years."

"We regard this as not unusual in the weather cycle over the last 8,000 years," Bloom said.

"There is no evidence for natural cycles doing that," Trenberth responded. "And there still has to be a source of energy to melt the ice. As scientists we know that this is associated with global warming and changes in the composition of the atmosphere. What he is saying is utter nonsense."

A Guardian blog investigation raised questions about the source of Pile's £2,000 a month salary after documents submitted to an appeal against building wind turbines in North Devon, which is not Bloom's constituency, claimed that he was contracted to the Europe of Freedom and Democracy (EFD) Group.

Bloom said: "He is on my staff and my website and his wages are paid as part of my secretarial research allowance. That is the reason – or one of the reasons - why I'm significantly better informed on this subject than most MEPs."
